IMPRVMENT IN PRESSES FOR COTTON, 8m.

The Schedule referred to in 'these Letten Patent and making part of the same.

To all whom it may concern:

`that the following is a full,clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification, in which- Figure l is a "ertical longitudinal section of my improved press, taken through the line :c x, fig. 2.

'Figure 2 is au end view of the same, partly in section. through the line y y, fig. l.

`Similar letters of reference indicate corresponding parts.

My invention relates to cotton-presses. of that class in which the lever or followeris pivoted at one end and raised and lowered by ropes, and

My improvement consists in providing a Vpress in which' the lever is raised by the rotation of the winding-drum, and is lowered, or forced downward to compress the bale, by rotatingvthe same drum v in the opposite direction.

The construction and arrangement of parts whereby this is affected,v is hereinafter fully described.

A represents the floor, platform, or ground upon which the press stands.

B is the block upon which the bale rests while being pressed, and which should be surrounded with a box, to give the desired shape to the pressed bale.

C is the block, which is pressed down upon the upper side of the bale to compress it.

The blocks B and (l are -grooved in the ordinary manner, to receive the bands or hoops of the bale.

. [lhe block C'is attached to or connected with the lever D, so as to be forced downward to compress the bale by the downward movement of said lever.

Ihe rear end of the lever D is pivoted to and between the standards E, which are strongly framedtogether, and securely supported Iand braced in a vertical position.

The forward end of the lever D passes and moves up and down between the standards F,tl1e upper ends of which are connected and held in their proper relative positions by a cross-bar, and which are securely braced in an upright position.

G is a rope or chain, the end of which is attached to the block of asingle fixed pulley, H, suspended from the cross-bar of the standards Il.

The rope G passes down and around a pulley, d', pivoted in a slot formed in the forward end of the lever D, up and around the pulley H, down and around a pulley, I, pivoted beneath the surface of the lfloor platform or ground A to some suitable support, and

thence along a channel beneath said surface to the drum'or vertical shaft J, around which it is wound, and to which its'end is attached.

K is another rope or chain, the end of which is at' cached to, and which is wound around the drum. or shaft J in an opposite direction from the rope-Gr, so that one of the ropes Gr K may be wound upon said drum or shaft J as the other is unwouud from it.

The rope K passes from the drum or shaft J to and" around the pulley L, up and-around the pulley (Z2, pivoted in a slot in the forward end of the lever D, down and around the single fixed pulley M attached to the foundation-frame of the standards F, and up, and is attached to the end of the lever D, so that, by turning the shaft or drum J in one direction ,the lever D will be drawn downward to compress the bale,`and, by turning said drum or shaft in the other direction, the said lever will be drawn upward to release the compressed bale'and allow another one to be placed in the press.

I he upper end of the drum or. shaft J projects above the surface of the loor or ground A, and to it is securely attached a lever or sweep, N, to the opposite sides of the outer end of which are attached hooks for the attachment of the whietree with which the horse is to be connectedfso that, by. shifting the whietree from one side to thc other of the sweep or lever N, the levcrD may be both raised andlowered by the direct vdraft of the horse, thus enabling the pressto be worked much faster than presse-s otherwise constructed. y

The upper part of the drum or shaft J is provided with a double-lever pawl, O, which takes hold' ofthe ratchet-wheel l? attached to the upper bearings for said shaftor drum J, so as 'to hold it securely in any position into which it may be revolved, in whatever direction it-may be moving.

Having thusdescribed my invention,

I claim as new and desire to secure Patent- An improved press, formed by the combination of the blocks B and C, lever D, uprights E, standards E, ropes or chains G and K, pulleys H dl I and L di M, drum or shaft J and sweep or lever N, the doublelever pawl O, and ratchet-wheel P, with the platform A, each of said parts being constructed, arranged, and

by Letters operating as shown and described,= whereby the'jleveris raised or lowered according to the direction of the rotation of the drum. l

The above specification of my invention signed by me'this 25th day of November, 1869.
